<P CLASS=para>
This interface defines the methods necessary for a class
that consumes image data to communicate with a class that
produces image data. The methods defined by this interface
should never be called by a program directly; instead, they
are invoked by an <tt CLASS=literal>ImageProducer</tt> to pass the image
data and other information about the image to the
<tt CLASS=literal>ImageConsumer</tt>. The constants defined by this
interface are values passed to the <tt CLASS=literal>setHints()</tt> and
<tt CLASS=literal>imageComplete()</tt> methods.

<P CLASS=para>
Unless you want to do low-level manipulation of image data,
you never need to use or implement an <tt CLASS=literal>ImageConsumer</tt>.
